Running R script using Shell in Slurm

The test shell script: submit_test.sh

R script: test_hpc_parallel.R

To run the R script using conda environment, the shell script:

1
2
3
4
5
6
7
module purge
module load anaconda3/2021.11
conda activate /home/224030234/R/R4.4-syf

cd /home/224030234/R
#run the application:
Rscript test_hpc_parallel.R

Following error will occur:

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
   - bash
   - fish
   - tcsh
   - xonsh
   - zsh
   - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'.

To solve this, source conda.sh before activate, and use the full path for the R scipt.

The revised shell script:

1

module purge
module load anaconda3/2021.11
source ~/anaconda3/etc/profile.d/conda.sh
conda activate /home/224030234/R/R4.4-syf

#run the application:
Rscript /home/224030234/R/test_hpc_parallel.R

Others

  1. conda install freezing
    When install r-pkg, solving environment freezing often occurs, to solve this, replace conda install with mamba.

    What is mamba

  2. conda channels operations

    1
    2
    conda config --show channels # show current channels
    conda config --remove channels defaults # remove defaults channel

    To add new channels:

    1
    2
    3
    vim ./condarc
    # add in condarc via vim
    conda config --show channels # check channels added status
